IMPROVEMENT IN SIIUT'I'LE-BINDEB. FOR LOOMS.

-W r TO ALL WHOM IT MAY CONGERN:

Be it known that we, Joint C. POLAND, -Jr.oi' Auburn, and BENJAMN COTTON, of Lewiston, all in Androscoggin county, Stute of Maine, have invented jointly certain newv and useful4 Improvements in Shuttle. Binders; and we do hereby declare that the following1 taken in connection with the drawings whichnaocompany and form part of this specification, is a description of our invention suilicicnt t0 enable those skilled in the 4art to practise it.

Our invention relates to the detail of the construction and arrangement of that part of a loom by which,

at the end of the shuttle-race and in the shuttle-box, the shuttle is arrested in its iiight, said part being known as a shuttle-binder, and being already constructed in various forms. Our invention consists in making the shuttle-binder in the form of a lever pivoted or fulcrumed 'between its ends, when these--are provided with adjustable set-screws; and it further consists in attaching the pivot or fulcrum of such a lever shuttle-binder to a support made adjustable by having the threads of a screw formed thereupon.

The drawing shows the embodiment of our invention in plan, a representing'a portion of one side oi" the shuttie-box with which our binder is connected. The binder itself` is marked b, and is av lever (preferably of metal) lpivoted at c, so as to vibrate thereon to any extent permitted by the adjustment of the set-screws d d. The fulcrum c is attached to a support, e, made adjustable by'having screw-threads out thereon,l so that the support e may be screwed directly .into theside a, of the shuttle-borner, as we prefer, and us shown in the drawings, may pass directly through said side, and may then be adjusted with reference thereunto by turning the nuts f j". The ends of shuttles vary somewhat in size or diameter, and also in the taper ot" their ends, so that it is highly desirable to have binders designed to operate upon said ends arranged to suit the various conditions of' diameter and taper of such shuttles as arelikcly to be used in any given loom, especially as the sizes and taper of shuttle ends vary fromlthe effects of wear. To adjust the inclination of the operative face of our improved shuttle-binder to suit the taper of anygiven shuttle, the screws ff' are manipulated in a way which is suiciently obvious and to any reasonable extent. The binder-piece b is made of such'a form as to have the inclination of its' operative face correspond to the average taper of the 'ends of the shuttles to be used there with. Suppose this operative face to extend between the dotted lines :c andy, and the shuttle employed to have its end somewhat more obtuse than usual; then, by retracting screw d and projecting screw d, the angle ofthe operative face of `the binder will be changed with reference to the line of the sh-uttles iiig'bt. If the ends of the shuttle are a little more acute than usual, then the angle of the operative face of the binder is adjusted by retracting screw dland projecting screw el. A In any adjustment of the binder, care must be taken to cause one of said screws to force the opposite end of the binder against the other of said screws, so that the binder shall be rigidly held without chance Afor vibrations or play. To adapt the binder to shuttles of various sizes oi' diameter or cross-sections, the whole of the binder is retracted from or projected toward the 'opposite side of the shuttle-box, this being accomplished by turning the whole binder `and its supporting-screw, e, "or by adjusting on the screw'e the nuts fff, the screws d d' being ladjusted ,by manipulation to accord withjthe changed position o i' the binder. yThough but one end of the binder-lever b is directly 'operative upon the shuttleend, we prefer to make both ends of the lever symmetrical, so that it may be changed end for end, both for convenience and to aiord a double wearing surface.

We claim ashutt-le-binder made as alever, pivoted. at or near its centre, when arranged with adjusting screws o2 d', by which the angle of the binder can be changed and the binder can be fixed in position, substan' tially as described. Also, inthe arrangement claimed above, mounting the pivot-of the binder lon a screw, by which the distance of the whole binder is adjustedr with referencerto the opposite side of the shuttle-box.
